and causing the same to ring, the, invention consisting in the construction, combination and arrangement of devices hereinafter de scribed and, claimed.

The object of my invention is ,to provide an improved form of engine, adapted to be operated by compressed air, steam. or

other fluid under pressure and which engine is cheap and simple in. construction, is

adapted to be readily attachedto one side of the stand or frame onwhich ahell is mounted and to be connected to the crank arm of the bell for swinging the latter.

In the accompanying drawingst-Figure 1 is an elevation of a locomotive bell ringer constructed in accordance with my invention, showing the same attached. to a loco motive bell in operative relation thereto. Fig. 2 is an elevation of the same at right angles to Fig. 1. Fig. 3 is avertical central sectional view of the engine, the piston, the piston rod and. the valve being shown in elevation. Fig. 4 is a' transverse sectional view on the plane indicated by-the line a-a of Fig, 3. I

In accordance with my invention, I -provide. a cylinder 1 which 1s here shown as formed with an integral, bo,tt0n1 'or' lower head 2 and a detachable upper'head 3, the latter being secured by bolts 4 to a flange 5 with which the cylinder is provided. On opposite sides of the cylinder at a suitable distance from its upper end are supporting arms or lugs 6 which are adapted to be bolted or otherwise suitably secured to one side of the frame 7 in which a locomotive bell 8 is mounted. In the bottom of the cylinder is a drain opening 9 provided with a plug 10. At one side of the cylinder is a connection 11 to which the air supply pipe from the air brake apparatus of the locomotive on which the bell and its ringer are used may be attached, to enable the compressed air from the air brake apparatus to be used as the motor fluid for operating the Specification of Letters I 'atent. ap lication filed g t 27, 1913.

municates with the let port 1} which isat a slightly lower plane than the port 12, asecond port 15 which is cylinderthrough an in: p j

spaced a slight-distance below the port 14 and thesaid passage also communicates with the lower end of the cylinder through a An exhaust port is here indicated in the same side of the cylinder with the passage 13 and located the cylinder. HA piston 18 is fitted in the bore of the cylinder fornvertical movement therein and is provided with spring packing rings 19. The piston rod 20 which extends near the upper end of upwardly fron the piston'passes through an opening in the center ofthe upper head 3. end with a,

and'is provided at its upper reduced extension 21, the upper side of which is formed with a substantially semicricular recess 22. 1 This extension is also provided with a transverse opening 23.

The piston rod is provided near its lower end with a pair of transverse adjusting openings 24-25, the. latter slightlyabove the former and is also'provided at a suit-'- abledistance from its upper end with an opening 26.

. A tappet pin 27 which is hereindicated as a spring cotter may be placed either in the opening 24 or the opening 25 and a similar tappet pin 28 is placed in the opening 26.

I also provide a valve 29 which is tubular in form and is provided near its upper and also its lower ends with packing rings 30 so; that an annular circumferential channel 31 is formed medially around the said valve. This valve is fitted for vertical reciprocating the piston, between the tappet pins 2728 and the piston rod extends through and is verticallymovablein the said valve. The length of the space between thetappet pins exceeds the length of the valve so that as the piston moves upwardly or downwardly, one

, of. its tappet pins as'it nears the end 0f;its' i I stroke engages the valve and, hence,-.moves the latter with the piston, the initialmove- -ments of the piston being independent of the valve as will be understood. 'j i I 100 movement in the bore of the cylinder, above The crank arm 32 of the bell has its wrist 32 engaged in an elongated slot 33" of an arm 33 which forms an upper extension of a pitman 38, the pitman being screwed to the lower end of the said arm and having a lock nut 33. At the lower end of the pitman is aball 34 which fits in the recess 22 of the piston rod and the upper side of which is engaged by a sleeve 35 which coacts with the recess 22 to form a socket for the reception of the ball The lower end of said sleeve fits on the reduced portion of the piston rod and is secured thereto by a bolt 36 which passes through the opening 23 and also through openings in opposite sides of the sleeve. The slotted arm 233* permits the bell crank to make a complete circle when the bell is swung hard allowing the air to exhaust from under the on the opposite side and then down through the passage 13 and the port 16 to the lower end of the cylinder and under the piston. driving the piston up until the lower pin 27 strikes the lower end of the valve 29 and moves the valve upwardly, thereby causing the valve to close the port Hand open the second port 15, thus cutting off further supply of compressedair to the cylinder and piston through the valve to the top of the cylinder and out through the exhaust port 17 to the atmosphere. This upward movementof the piston throws the hell up; the weight of the bell then moves the piston downwardly and just before it gets to the bottom of the cylinder, the tappet pin 28 strikes the upper endof the valve, moving the latter, downwardly and thus causing the valve to close the port 15 and reopen the inlet port 14. Port 17 is open to the atmosphere at all times and any leakage by any of the packing links is free to escape. The port 12 is never closed by the valve. 'It wil' be observed that the valve is balanced and, hence, it moves very easily in either diroction.

To vary the length of the stroke of the piston, the lower tappet pin will be placed in an appropriate adjusting opening, 24 or 25 of the piston rod, as the case may be.

I claim In apparatus of the'class described, a cylinder having a medially located intake port on one side, an exhaust port near the upper end and a passage in one wall communicating with the lower end of the cylinder and having an inlet port near the'center of the cylinder and a second port below and spaced fromthe inlet port, in combination with a piston in the cylinder having a rod extending through the upper head thereof, a tubularvalve fitted and movable in the bore of the cylinder and also movable toward and from the piston rod, said valve having a bore extending therethrou'gh from end to- I end ofgreater diametenthan the piston rcd and also having a pair of spaced .heads' forming an annular chamber around the said'valve and with which the intake port of the cylinder communicates, and tappets on the piston rod to successively engage and move the valvea's the piston nears the limit of its stroke, one of said tappets serving on the up stroke of the piston to cause the lower head of the valve to close the inlet port and open the second port.

In testimony whereof I afiiX my signature in presence of two witnesses.
